[Question] - Felicia 1.3 MPi Alex HVAC unit
Yup, that would be the case for a PS-equipped one. But there were no 90A alternators (at least not the original ones), that came with a 4-groove pulley. So either they had to use a 90A with a 4PK belt and pulley on the non-PS setup (that would be the better option). Or they did the dumbest thing and decided to stick with the 70A for the non-PS cars. That's what I'm so afraid of, because the bracket is clearly a little different than yours in some kind of way, if you look at the comparison of the engine bays above.

I'm kind of starting to be afraid that this might not be the layout of the bracket that I will be getting from the donor car. It is similar, but if you look into the installation guide, there's virtually no space or even any mention of mounting the PS pump with it. It's not even in the belt diagram which was included in it, which is strange in itself. And because the original car before the dealer conversion was non-A/C and non-PS, I suspect that because the guide does not tell you to discard the alternator, and still uses a 4PK belt (albeit a longer one) as well, there is a possibility, that the kits for non-PS cars retained the original alternator for non-A/C and non-PS cars, which were 70A. 😕 If that is the case, I would have to either try and source the larger bracket that you have on your car, or try to make it work in a different way.

[Question] - Felicia 1.3 MPi Alex HVAC unit
You're right,@Papez, it really can be confusing. I do have to say though, that I actually really like Alex's approach, especially compared to the horrific solution by Diavia, because over here, both the compressor and the alternator are completely out of harms way, and virtually no mechanical damage from outside can be inflicted there. Also, the piping seems to be very easily accessible even without having to go underneath the car. That being said, the original unit (IIRC manufactured by Siemens) does have the piping placed in such a way, that replacing the alternator is a substantially easier job, compared to the situation with the Alex unit. But I don't really mind that, thankfully. As for the alternator, it's exactly like you said. I will try to source and mount the 90A alternator (only replacing the pulley on it with the 4-groove). Of course, on the PS version bracket, it has to be supported, but on the non-PS, I'm unfortunately very unsure about it. Do the mounts on for example the two original Magneton alternators (the 70A and 90A ver.) differ by a lot? Because from outside, apart from the pulley itself, they do look very similar.

[Question] - Felicia 1.3 MPi Alex HVAC unit
Hey guys, wishing all of you another wonderful day. Today, I just wanted to share an interesting fact that I've stumbled upon while studying the entire Alex A/C assembly in the engine bay, and maybe provide a little bit of insight for anyone who might read the topic in the future. It regards the difference between a power-steering (PS) version and non-power steering (NPS) version of the Alex kit. Now, since the official Alex installation guide that was provided earlier by @Thefeliciahacker mentions on its cover page, that it was meant for cars with PS, I initially thought that the bracket shown there was unified for both models, but it seems like that is not the case, and not just because the PS pump is not even shown in the belt diagram there. If you take a look at the pictures below, which compare my non-PS Felicia Family donor car's engine bay (first two pics) with @Thefeliciahacker's PS-equipped Felicia Sport Line (third pic), there seems to be a bit of a difference in the positioning of the A/C compressor, as not only does the PS version probably get a larger 6-groove compressor clutch and a longer, wider 6PK belt (the NPS version retains a narrow 4PK type belt, and for some reason, according to the guide, it's not even required to discard the original non-A/C 70A alternator, which might be a very bad idea in my opinion, as the system simply must be too power hungry for that, right?), but the compressor itself actually sits a bit higher to accomodate for the PS pump, which, if I'm not mistaken, is located underneath the alternator at the bottom of the engine bay. This suggests to me, that the bracket itself must be a completely different part for each of the two versions. There's also the additional support bar above the compressor, which is secured by the rear-leftmost head bolt, and which the NPS version does not get at all (and it is, again, not even shown in the installation guide). I don't know whether any of you have experience with the NPS version of the kit, but the difference did pique my interest quite a bit, as I haven't really seen anyone compare the two, and just initially assumed that the Alex kit supports the addition of PS in all 1.3 engine variants of the set. Not that I would be planning to install that, but it might be good to know for someone. Apologies to all of you for the sub-par quality of my photos, BTW.

[Question] - Felicia 1.3 MPi Alex HVAC unit
Many thanks for this heads up, @D.FYLAKTOS, I think there might've been a copper washer in the original set for the 3-pin. I'll check the box though, and if it is not, I'll make sure to order the right one. The fairly detailed Czech book by Mario René Cedrych that I have checked states, that unlike the 2-pin variants, which were truly made by Metra Šumperk, the 3-pin version was supposedly manufactured in Germany by Wahler (it did look and feel very high quality as well, which caught me by surprise when I got it). As for the wiring, I'll take a good look on the donor car when we'll be disassembling the unit and related parts, and of course document everything carefully with pictures so that there's a much smaller chance of messing up during the reassembly. I might initially reuse the fan from that car just to make sure that everything's fine, and replace it later on in the process of fine tuning everything. Perhaps while trying the intelligent fan wiring setup proposed by @Thefeliciahacker.

[Question] - Felicia 1.3 MPi Alex HVAC unit
Hello, guys, wishing you all a nice day, once again, I would first like to thank each and every one of you for all of the feedback provided for the topic of this post so far. It's been immensely valuable and insightful for me. I wanted to ask you all about one more thing I'm not entirely sure about, which would be the thermoswitch for the fan. Now, at the moment, I do know that there were at least 2 different types of the 2-pin switch, each one tuned for a different climate that the car is to be driven in. At the moment, on my car, I have a brand new original one with the higher activation temperature of about 95°C on the temperature sensor, and the car's been running just fine with it. You can see that one in the 1st attached picture. However, from what I know, all original air conditioner equipped cars (and diesel-engined Felicias for that matter) got an entirely different, 3-pin variant (please see the 2nd attached picture), presumably because of the 2-step fan activation. I actually have a brand new original one in that version available for my car as well. But the official Alex installation manual does not mention that the switch would need to be changed, and as it was designed to be installed by a dealer on an originally non-A/C car, I presume, that the wiring there may still be designed for the 2-pin switch. As such, my question is, which one of the two general types is compatible with the wiring of the Alex A/C unit. Again, thank you all very much.

Very well, then, since there's an actual difference, I'll try to source that blue original one. The non-original thermostat housing on my car is starting to sweat ever so slightly from the outside anyway, so that part is definitely due for a change very soon, and the A/C installation process might be a really good chance to proceed with it. Thank you very much for this valuable piece of info.

[Question] - Felicia 1.3 MPi Alex HVAC unit
Hello, my fellow Czech enthusiast. Unfortunately, I haven't looked there, because I managed to find @Thefeliciahacker's video on YouTube first, and that one was so helpful, that there was basically no need for me to look through the Czech forums, so I just asked over here, as both of our Greek friends really know quite a lot about the Alex A/C in particular. Especially the original Alex installation guide is an absolute lifesaver for me. I will have to check the connector and the wiring for the fan when I'll have taken all of the components off the donor car (hopefully this Saturday, if everything goes well). But it is really good to know, how the different fan versions operate. At the moment, my car still has the more square shaped 2-pin connector little non-A/C PAL fan which was identical to the older Å koda 78X and 74X lineup models. Of course, I'll have to take the entire bunch of wiring harnesses off the car as well with the A/C. If necessary, I also have 2 professional electrician friends, so we can work out a completely custom setup as well if we want to make the cooling fan behave in a different fashion for example. But that diagram from @Thefeliciahacker might very well be exactly what I am looking for, as it seems to be very carefully designed. That Autopal radiator was really hard to source, especially this particular A/C version, so as long as the OEM A/C shroud and 150/250W fan fits there, I'll be more than happy, especially in our climate. I'll also make sure that it lasts as long as it can even in the rough winter conditions that sometimes come over here. I do have one more question though. On most 1996 and newer Fellies, a thermostat with plastic housing (a very unreliable design from my experience over the years) was used. And these thermostats came in at least 2 different variants from the factory. Now, on the donor car, the regular non-A/C version was retained... that one has the yellow ring on the temperature sensor. However, cars equipped with factory A/C units used an identical looking type, but with a blue ring (please see the attached picture). My question therefore is, whether there actually is any kind of difference between the two. Because if there is, I currently have a rare chance to get a brand new original one of the blue variety, and it might be a good time to get it. Once again, thank all of you guys for the help. It's not an easy process to transplant the unit, but I'm really satisfied with how well it works, and with all of you having my back like this, I really do feel much better going for it.

[Question] - Felicia 1.3 MPi Alex HVAC unit
According to a quick research of these 2 part numbers, it would seem that there is a mistake in the description of the 2 fans. The "0130107262" seems to be the OEM non A/C, 2-pin variant (no middle pin) used by Å koda for warm climate Felicia models. The "0130109237" should be the dual-speed, 3-pin variant used with A/C equipped cars. Both variants tend to come up when searching for one or the other, but this is what seems to be the case there.

[Question] - Felicia 1.3 MPi Alex HVAC unit
Thank you very much for the answers, guys. I really appreciate all the suggestions, as well as the extensive documentation provided by @Thefeliciahacker. That really will help a lot during the removal from the donor car. As the A/C will be going into the car at some point before next summer (probably at the end of the next winter season, I will give all of the details about the fan a good thought first, and get everything prepared with as much precision as possible. But seeing that I already have the nice OEM shroud and Autopal radiator, I will probably go with the "MAHLE CFF 7 000S" 150W/250W fan (in the picture), as that one should be sufficient for this use in our climate, and should fit the shroud that I have perfectly.

[Question] - Felicia 1.3 MPi Alex HVAC unit
Hello, everyone, I am currently in the process of purchasing an Alex air conditioner (which, if I am not mistaken, was an optional set offered by Škoda dealers back in the day). It is a complete working set for the 1.3 MPi engine, very much like the one you see on the car in the first 2 pictures below (although in seemingly better condition), with the only difference being that the version I am about to buy was most likely used for cars without power steering, as the donor car which it is currently in does not have it (just like mine). Which gets me to the biggest problem, as I am about to be removing the complete set from the donor car myself in the coming weeks. As such, I decided to ask all of you experienced enthusiasts out there. Do you have any tips or tricks that I should know before removing the system from the donor car and then installing it into my own Felicia? Or perhaps any original schematics for the Alex unit that I could use? I tried to look for such documents on various forums before, but it seems that the files are fairly hard to come by nowadays, and the schematics for the OEM A/C unit are of course unfortunately not very helpful in this case. 😔 And possibly one more question. Can this type of air conditioner work with the "warm climate" 2-pin fan (6U0 959 455C, probably identical to the 165 959 455S fan for the 1.6 engine), in the 3rd picture below) or the late model 3-pin fan (6U0 959 453B) which were supposedly used with the OEM unit? Or does the fan motor included with the set have a proprietary connector or any special characteristics? It may be different on the donor car for me of course (there's a very large fan with a thin motor and a simple circular shroud on that one, kind of similar to the 1.9D OEM fan, but with a simpler shroud), but I would like to know, which connector your radiator fan motor on the Alex unit uses, as I already own a brand new OEM fan shroud (also in the 3rd picture), as well as the OEM Autopal radiator (6U0 121 251C) for the A/C equipped model that the shroud mounts onto very nicely. Thank you all very much for your help. 😄

Just a little Hello from me and my "Mel" :)
Hello, everyone, let me extend my greetings to all of you, the wonderful members of this forum. My name is Ondra, I'm 23 years old and I come from the very home of most Å koda cars, the Central-Bohemian Region of the Czech Republic. My car is the one found in the attached picture, a petrol green 2001 Å koda Felicia LXi ("Trumf" edition), which is powered by the 781.136M engine (AKA 1.3 MPi 50kW / AMH). It's been nicknamed "Mel" because of the original license plate combination. I'm looking forward to learning something new from you all, as well as perhaps using some of my own knowledge to help some of you in return.
